NAIL-TBANSFERRING MECHANISM.

Application 'filed October 2, 1919. Serial No. 327,967.

ToaZZ whom it may concern. i

Be it known that LJOSEPH ,H. Porn, a citizen of the United States,residing at Hamilton, in the county of Essex and State of Massachusetts,have invented certain Improvements in Nail-TransferringMechanism, ofwhich the following description, in connection with the accompanyingdrawings, is i a specification, like reference characters on thedrawingsindicating like parts in the several figures.

Thisinveirtion relates to mechanism for transferring .nails,.as from thedistributing mechanlsm of a heel-attaching machine to the nail-blockfrom which they are driven. In my application for Letters Patent filedApril 24:, 1918., Serial No. 224,428, means is disclosedfor locking suchtransferring o1 loader mechanism, asit is commonlytermed, in itsnail-receiving position under the control of the heel and top=liftholder, so that the loader mechanismcannot be operated to deliver asecond load of nails to the nailblock until saidholder has performed itscomplete movement, and consequently until the load of nails previouslydeposited in the nail-block has been disposed of. In some c'lassesofwork, however no top-lifts are ap plied to the heels, and there is noholder movement to effect the control of the loader block, 1

such conditions in view, an object of this invention is to furnish novelcontrolling, means for the nail-transferring mechanism. For thispurpose, ina machine having controllable actuating mechanism, I controlthe transfer mechanism with said actuating mechanism. For example,nailing mechanism be actuated by power mecha-- nism,.and in the-controlof the latter to start 1 or :stop the operation of the machine, theaction of the loader mechanism may also be determined, it being hereshown as latched in its nail-receiving position and released byconnection to the controlling means, as the starting lever, only afterthis has been op erated to performa nailing operation. This. insuresthatthe previously delivered load of nails will have been utilized and thatthe nailing mechanism is ready for the delivery of another load. Uponrelease, the control of the transferring mechanism may be renderedtemporarily ineffective, as by a spring pr other .means acting to movethe transferring mechanism away from the latching arm 42, which issecured to the spindle 22 by rich...

device. As the operator may sometimes desire to move the loadermechanism without a starting the machine, independent means, as aplunger operating upon the latch, is also provided for releasingtheloader mechanism.

In the accompanying drawing illustrating one embodiment of my invention,

Fig. 1 is a front elevation of a'heel-attach For the purposes of thisinvention, the

portion of the starting lever and general construction of the machine isnot important. ltwill be sufficient to say that a frame 10 has fixedupon it a nail-bloclr12,

with the openings of which co-operate re-' ,ciprocatory drivers .1 1-and to which nails are transferred from a distributing mec hanism 16 bya loader mechanism 18. To actuate the drivers and like movable parts ofthe machine, power is applied under the control of a s'tartinglever 20.This is fulcrumed upon upon a spindle 22 mounted to turn in the frameandhaving connections 24 to the usual clutch mechanism (not shown.)

l/Vhen the loader arm 26 has; the openings of its nail-carrying blockproperly :alined with the delivery tubes 28 of the distributor, it islocked in position bya latch .29 ver-p tically movable in a casing 30mounted upon the end of a bracket 32 projectingfrom a, portion of theframe. This latch engages-an.

opening 33 in. a block 3i adjustably fixed to the upper side of theloader arm by a screw 36 passing through a slot 87. Situated above,

the latch in the casing and urgingit toward the opening 33 is a spring38. The latch is connected by a Wire or other flexible mem-j ber 10 tothe starting lever by .means'of'. an

a set screw 4e. The arm is divided at its outer extremity, and betweenits portionsthe wire is clamped by a screw 46, giving a capability foradjustment as to length. The opposite end of the wire is fixed to thecenter of the upper extremity of the latch 29. Sur rounding the wire isa flexible guide tube 48,

The oppositeextremity of the guide tube is held in the opening at the top of thecasing 30,- through which, the wire 4K0 passes,and furnishes an abutmentfor the spring 38. 1 p I Assuming that the loader arm has been swungover the nail-block and has delivered a load of nails thereto, theoperator moves it back beneath the distributing mechanism.

,When this is reached, the opening 33 is beneath the latch 29, whichenters it, looking the loader arm against reverse move- 11161111. Atthis time a downward projection 55' from the loader arm presses againsta contact member 56 carried in a casing 58 upon a spring-pressed lever60,

the movement of which may be utilized to start the operation of thedistributing mechanism 16 to supply a load of nails to A shoe being inposiera-tor depresses the starting lever 20 to throw in the clutch ofthe machine and drive the nails contained in the nail-block openingsinto the heel of the shoe. As the lever is lowered, the arm 42 is turnedin an anti-clockwise direction (Fig. 2), ap-

plying tension to the wire lO and raising the latch against its spring38 from the opening in the loader arm. vWhen the loader arm is thusreleased, the contact member 56 moves it to carry the opening 33 out ofalinement with the latch, so that the arm will not be immediatelyrelocked upon the release of the lever by the opera tor. The nails inthe nail-block have now been disposed of, and the loader arm may becarried over its openings to provide it VVh-ile, ordinarily, the loaderarm should not be permitted to he movedfrom its nailreceiving positionwhile there are nails *in the nail-block, certain occasions may arisewhen its release is desirable under these conditions. mechanism mightfail to fully supply the loader block in which case the operator wouldWish to obtain access to it to insert the missing nails by hand. Toenable this to be done, manual means is-provided for freeing the latch,this being shown as consisting of a plunger (SQ/mounted to slide in theopening 33 below the latch and re- "tained therein by an enlarged head.This For example, the distributing with the actuating'mechanism andinclud flexible connections transferring mechanisnr a:
